Instruction manual

Command Mode

This feature allows data terminal users to originate data and voice calls and change (or view)

their data port options.

(Refer also to the general description of the system’s data features in “Data Services

Overview”).

Command Mode supports digital data endpoints connected via Asynchronous Data Units

(ADUs) to ports on a Data Line CP (TN726). Command Mode also supports, with certain

restrictions, users of the STARLAN Interface Circuit Pack, ZTN84.

Command Mode is invoked from a data terminal in the idle (on-hook) mode by:

Terminal Optioned For Autobaud

Terminal Not Optioned For Autobaud

Enter Break followed by Return

Enter Break

The terminal then displays the Command Mode menu:

Menu items are chosen either by positioning the cursor under the desired item (by typing

“space” characters) and entering a Return, or by typing the upper-case character in the

menu field (e.g., type “D” to choose data terminal dialing or “O” to move to the options

sub-menu). Once a user has entered Command Mode, the terminal is considered off-hook

and busy to incoming calls until it returns to the idle mode.

<Data call> or <place Data call>:

Refer to the “Data Terminal Dialing” feature description for information on how to dial from

your terminal. Once a data call has been set up, either the “Disconnect/Recall Sequence”

(see the Permissible Options, Table 2-G) must be sent or <Hangup> selected from the above

menu to terminate the data call and return to idle mode. If a data call is not answered, the

caller must disconnect by sending a Break.
